    Default What to do for a Barlow?



    Hi all,

    Wading into the murky grounds of eyepiece upgrades. I'm looking at over the next few years upgrading my optics where possible. This isn't a passing fancy, so would prefer to not be upgrading my eyepieces every few years, so am intending to move straight to Baader Hyperions, and will do so slowly.

    With this in mind, what Barlow would people recommend to go with this? I've seen Celestron omni and Tele Vue seem well liked, and the GSO is also rated (I have a GSO plossl, which produces nice detail, but has irritating eye relief), but at a cheaper price than the previous two.

    I'm quite surprised to see the relative affordability of the Baader Barlows, and wondered if anyone had dealt with them? Is it worth trying to stick to the same brand for sets (that is, can the coatings etc. of different brands 'clash' or am I thinking too much about this?)?

    I see that the Baader Barlow claims to be optically matched to the Baader Classics... Thoughts?

    Fairly tempted to go for the Baader...

    Many thanks in advance!

    I have not tried the Baader Barlow, but I am not a fan of the Hyperions. They do not perform well in a fast Newt. I know that is not the scope you have, you have the 5" SCT and the Hyperions should work OK in that scope. But if you ever do get another faster scope, especially a Newt, you will be disappointed with the Hyperions. You also can get other EPs cheaper that will perform just as well in your SCT or any future scope. The so called versatility of differing focal lengths by using the fine tuning rings is much more of a hassle than a benefit and all of these are 1.25" EPs that will also fit in a 2" focuser but are still only 1.25" EPs.

    A much better EP is the ES 68s which will work very well in any scope including the picky fast Newts. At a slightly smaller FOV but more affordable than the Hyperions is the Celestron X-Cell LXs which will also work well in any scope. I found the Hyperions to be soft even in my SCTs with serious field curvature in faster scopes and either of these other two (ES 68s or X-Cell LXs) were much more crisp even in my SCTs. Personally I think I would choose the GSO plossls over the Hyperions. I really like the Baader Orthos and their filters, but was very disappointed with their Hyperions. I just don't know about their Barlow and it may be very good, or it may not.

    I've only a few thoughts for you - there are others far more knowledgeable than me here.

    Usually I see folks who've started out with modest budgets and have gathered a few low or medium priced eyepieces and perhaps a Barlow or two. As they contemplate purchasing eyepieces of higher value, a caution may be offered about taking that high value eyepiece and using it with a budget Barlow. So, your intention to purchase Baader eyepieces fits perfectly with the purchase of the Baader Barlow.

    That being said, I don't think that there is any problem at all with mixing and matching brands. Just keep in mind that the quality of your observation will be controlled by the lowest quality component in the optical chain.

    I have recently started to purchase some higher priced eyepieces myself. For my budget, the Explore Scientific 82 degree FOV eyepieces have fit my need. Much better all around than the old Celestron Plossls that I have. I can use the Celestron 2x Barlow with any of my eyepieces, but I have to remember that it will be the lowest quality component in my optical chain, and I may not be happy with my observations.

    I hope this helps you a bit.

    The Baader barlow is matched to the Baader Orthoscopics so may not be a good match for the Hyperions.
    They do work well in a f/8 refractor with a Antares 1.6x and 2x though.
    Others on the forum have used the Baader barlow with different eyepieces so hopefully will add information.
    My only thoughts are sometimes one or two focal lengths from a set work well with a specific scope so try them first before purchasing something that may not work for you.

    Refractors kick arse precisely because they don't hide behind excuses. That is, they have no obstructions to hide behind. - Jon Isaacs (CN)

    I would advise against Baader Hyperions. They are descent EPs, but of older design which is outperformed by many EP lines, so you find better value somewhere else. Depending on you budget I would suggest to look for Explorer Scientific 82 and 68 degree lines, Meade 5000 UWA and HD60, or Celestron X-Cel LX as Ozman suggested.

    Baader Barlows are of good quality, but they are designed for specific line of products (i.e. Baader zoom EPs or Baader Classic Ortho/Plossl set). If you want good quality general purpose barlow I would suggest TeleVue 2x or 3x barlow.
